Abstract: Alcohol ethoxylate surfactants particularly useful in detergents are combinations of formulae HO.(EO)n1.R1 (Ia) and HO.(EO)n2.R2 (Ib) where EO is ethyleneoxy; n1 is 3 to 8; n2 is 4.5 to 9; R1 is c8 to C12 alkyl and on average C9 to less than C12; and R2 is C12 to C16 alkyl and on average C12 to C15; in weight proportions so the average carbon number in R1 and R2 is 10.5 to 12 and the overall average number of EO units is 4.5 to 8. Such combinations afford a combination of good surfactancy, particularly detergency, with low aquatic toxicity. Desirably, the composition is of mixed-alcohol ethoxylates, i.e. alcohol ethoxylates made by ethoxylating a mixture of alcohols to satisfy the requirements set out. The surfactants can be used in detergent formulations, e.g. for laundry and hard surface cleaning, for fibre, yarn and fabric scouring, or as emulsifiers.

Abstract: A furnace having sidewalls to form an enclosure to contain a melt. One or more burners are positioned to fire into the enclosure to maintain the melt and one or more charge wells are separated from the enclosure by the sidewalls. A charge of material to be melted is loaded into the charge wells and melted. Submerged openings defined in the sidewall circulate melt to the charge well(s) and to circulate the melt back to the enclosure. Submerged pumps effectuate the circulation. Flue gas openings defined in the sidewall(s) are configured to direct flue gas into the charge well(s) and onto the charge of material. Two opposed charge wells and pumps may be provided as wells as flue gas openings to heat the charge of material deposited into the charge wells. The flue gas openings allow flue gas to impinge onto the charge of material to be melted so that heat that would otherwise be lost in the flue gas is used to help melt the charge of material.

Abstract: A method of determining the scaling factor for a signed n bit binary number, where n = 2 e, includes the steps of dividing the number into a plurality of subgroups of at least two bits each; providing a plurality of subunits holding the respective subgroups of bits; and arranging the subunits in a hierarchical tree structure of units.  Each unit of a superior level receives inputs from units of a lower level, and each unit produces first, second and third output signals. The first output signal represents the most significant bit of the units in the associated hierarchy, the second signal indicates whether the bits in the associated hierarchy have the same value, and the third signal is an i-bit number representing the number of places less one that the bits in the associated hierarchy can be shifted. The index i is the same as the associated level in the hierarchy.

Abstract: Cette invention se rapporte à un procédée grâce auquel un système client et un système serveur peuvent coopérer pour restituer des vues d'un monde virtuel dans lequel navigue un utilisateur du sytème client. Le serveur envoie au système client une vue de référence et un modèle servant à extrapoler la vue de référence en réponse au mouvement virtuel de l'utilisateur. Le système client envoie au serveur un enregistrement du mouvement virtuel de l'utilisateur. Le système client et le système serveur effectuent tous les deux l'extrapolation de la vue de référence sur la base du modèle. Le serveur effectue également une mise à jour exacte de la vue de référence. Lorsque la vue de référence extrapolée s'écarte trop de la vue de référence mise à jour, le serveur envoie au système client la différence entre la vue de référence extrapolée et la vue de référence mise à jour, pour que le client puisse mettre à jour sa vue de référence.

Title: Improving the security of mobile telephones against eavesdropping
Inventor: WILHELM MICHAEL
IPC: H04M1/68
Filed: 1999-10-20
Abstract: A method of detecting an eavesdropping device (IC) which is interposed between a mobile telephone (MT) and a base station (BS2) and which accepts, as a purported base station, a call from the mobile telephone (MT) and then forwards it, as a purported mobile telephone, to the base station (BS2) involves storing data of the base stations (BS1, ..., BS5) used by the mobile telephone (MT) in the mobile telephone (MT). When a new connection is set up to a base station (BS2), the data newly determined during this connection setup are compared with the data to be expected for this base station (BS2) in view of the stored data. If the data differ, an error signal is generated in the mobile telephone (MT). This error signal may initiate a release of the connection with this base station (BS2) or trigger an alarm message to the user. This improves the security of, e.g., GSM mobile stations against eavesdropping.
